When user need to beat opening door body 2, user's handling handle 3 and by mounting cover 4 with trend the direction pivotable near trigger unit 34, the button 61 that is arranged on like this microswitch 6 on mounting cover 4 will compress with trigger unit 34, microswitch 6 is triggered, and controller is subject to will opening with booster opening door by accessory drive 8 driving gate bodies 2 after the triggering signal of microswitch 6.

Realize intelligent booster opening door according to the refrigerator of the utility model embodiment by the handle 3, drive unit 8 and the controller that are provided with microswitch 6, do not need the additional action of opening the door, when user's handling handle 3 opens the door, drive unit 8 promotes door body 2 with booster opening door, user is opened the door easier, promoted the convenience of product, practicality is good.

In an embodiment of the present utility model, wherein, the rear side of handle body 31 is spaced apart with the front surface of door body 2, forms a clearance space like this between handle body 31 and door body 2, and user's hand can stretch into wherein holds handle 3.Handle 3 also comprises handle pedestal 32, and microswitch 6 can be located in handle pedestal 32, and handle pedestal 32 can be protected microswitch 6 like this.One end of handle body 31 is fixed on a body 2, the other end of handle body 31 is fixed on a body 2 by handle pedestal 32, that is to say, the other end of handle body 31 and handle pedestal 32 are fixing, handle pedestal 32 is fixing with door body 2 again, and handle 3 is just firmly fixed on a body 2 like this.On handle pedestal 32, can be provided with installing hole 41, screw can be fixed on mounting cover 4, microswitch 6 and handle pedestal 32 on handle 3 through installing hole 41.In an embodiment of the present utility model, thereby can also handle body 31 and handle pedestal 32 be fixed on a body 2 handle 3 is fixed on a body 2 by screw.

As shown in Figure 6, one end of mounting cover 4 is formed with through hole 42, and through hole 42 is located at one end just right with trigger unit 34 on mounting cover 4.Microswitch 6 is fixed on the rear surface of one end of mounting cover 4 and the button 61 of microswitch 6 runs through forward through hole 42 just right with trigger unit 34.When user's handling handle 3, will make mounting cover 4 to the direction near trigger unit 34 namely near the direction pivotable of handle body 31, trigger unit 34 can contact and compress button 61 with button 61 like this, so just can trigger microswitch 6.

In an embodiment of the present utility model, the two ends of mounting cover 4 are respectively arranged with rotating shaft 43, are provided with the rotary shaft hole coordinating with rotating shaft 43 on handle 3, and wherein pivot axis is the central axis of rotating shaft 43.The rotating shaft 43 at the two ends of mounting cover 4 is located in rotary shaft hole, and mounting cover 4 just can be arranged on handle 3 and namely pivot axis of central axis that can spinning rotating shaft 43 like this.

Further, rotating shaft 43 is near a side of mounting cover 4.Be conducive to like this pivotable of mounting cover 4.In an embodiment of the present utility model, rotating shaft 43 is near the upside of mounting cover 4.

As shown in Figure 1-Figure 3, drive unit 8 can be located on the end face of casing 1.Drive unit 8 can promote a body 2 effectively like this, and drive unit 8 is located on the end face of casing 1 and is convenient to detachable maintaining, reduces the maintenance cost of refrigerator.

Certainly, the utility model includes but not limited to this, and drive unit 8 can also be located on refrigerator other effectively suitable positions of driving gate body 2.

In an embodiment of the present utility model, drive unit 8 can comprise drive motors and driving shaft.When drive unit 8 is worked, drive motors work and order about driving shaft move forward and door a body 2 back down, thereby user can easily easily beat opening door body 2.

The sealing when front end of driving shaft offsets or is spaced apart from each other to guarantee that a body is closed with the rear surface of door body 2.In embodiment of the utility model, the front end of driving shaft offsets with the rear surface of door body 2, and drive motors is started working like this, and the rear surface that driving shaft just can directly promote a body 2 makes a body 2 move forward and beat opening door body 2.In another embodiment of the present utility model, the front end of driving shaft is spaced apart from each other with the rear surface of door body 2, and drive motors orders about driving shaft and moves forward a segment distance like this, behind the rear surface of driving shaft pushing and pressing door body 2, makes a body 2 move forward and beat opening door body 2.

As shown in Figure 1-Figure 3, refrigerator can be side by side combination refrigerator.Side by side combination refrigerator comprises first body 21 and second body 22 that split around setting.That is to say, first body 21 and second body 22 are set up in parallel on left and right directions, and for example, as shown in Figures 2 and 3, first body 21 can be located at the left side of second body 22.As shown in Figure 1, handle 3 can be located at respectively on first body 21 and second body 22, that is to say, on first body 21 and second body 22, is respectively equipped with handle 3.Drive unit 8 is close to the front surface of casings 1 and is positioned at the intersection of first body 21 and second body 22.Driving shaft further can comprise the first driving shaft 81 for driving first body 21 and for driving the second driving shaft 82 of second body 22.Drive unit 8 can promote and open first body 21 and/or second body 22 easily like this.

Preferably, in the time that user pulls first handle 3 on body 21, drive motors drives the first driving shaft 81 to travel forward and drives the second driving shaft 82 to move backward, in the time that user pulls second handle 3 on body 22, drive motors drives the second driving shaft 82 to travel forward and drives the first driving shaft 81 to move backward.That is to say, when user pulls a handle 3 on door body, drive motors drives corresponding driving shaft to promote and opens a described door body, drive another driving axial simultaneously after motion to avoid opening described another body when user does not think to open another body simultaneously.So greatly improve the reliability of refrigerator.

Certainly, it should be noted that, in the time that user grips first handle 3 on handle 3 and second body 22 on body 21 simultaneously, drive motors can drive the second driving shaft 82 and the first driving shaft 81 to travel forward simultaneously and push forward first body 21 and second body 22 open.
